Abstract:

Presently, polymers are playing a significant role in aerospace research world over. However, the use of polymeric materials in primary structures of aerospace is still limited due to the high temperatures encountered by the aerodynamic heating in the case of aerospace. Therefore, thermoplastic materials are often used to replace parts of the engine which are traditionally constructed from metals. PEEK ( poly ether ether ketone) polymer, is increasingly used in the aerospace industry as a replacement for metal components, because it combines all these characteristics with easy processability.This paper mainly deals with the different properties of PEEK and the need for modifying its surface which can further enhance its adhesion characteristics.
